How impious the Arians are, in attacking that on which human happiness depends. John ever unites the Son with the Father, especially where he says: “That they may know Thee, the only true God, etc.” In that place, then, we must understand the words “true God” also of the Son; for it cannot be denied that He is God, and it cannot be said He is a false god, and least of all that He is God by appellation only. This last point being proved from the Apostle’s words, we rightly confess that Christ is true God.
